Referring to the drawing numeral 1 de- UNITED STATES- PAT GEORGE w. BERnAIiER, or s'r. cHAnnns MIssoURI,

rnnss;

To all whom it may concern:

Be it known that I, GEORGE I a citizen of the United States, residing'at St. Charles, county of 'St. Charles, Statef'of Missouri, have invented a new useful Press, of which the following is a specifica-' tion'; v p This invention relates to improvements 1n presses especially designed for, but not necessar ly restricted'to, the cementing ofv shoe-soles and, among others, has for an object the provision of a simple, compact, inexpensive and efficient machine of the character described which possesses great and unusual power of compression.

Other objects and advantages may be noted in the following parts of thisspe cification and the appended claims. I

In the accompanyingdrawings, in which like numerals referto like partsthroughin section, of the press, and Fig. 2 a side notes a stationary table or platformwhich may, be'rigidly supported in pos t on by braces or legs extending to the floorforin any other manner desired. Secured upon the upper surface of said table is 30 casting 2 provided with, sockets 3' at its opposite ends into which project set-screws 4 Disposed in sockets 3 are the free extremities ofshafts 5 whose opposite ends are detachably connected by cross-head 6 having set-screws 7 for its vertical adjustment relative to said shafts. Disposed be tween casting 2 and cross-head 6 are presserplates 8, 8? having oppositely inclined under surfaces 9 and 10, said plates being apertured at 11 for the passage of shafts 5- and retained in spaced relation by helical springs 12 mounted on said shafts. Projecting centrally through members 1, 2, 8

and 8 is a rod 13 whose upper extremity is 5 ratchet is slotted as at23 and is normally connected with plate 8 and whose lower end is pivotally secured as at 14: to a treadlelever 15 hingedly supported at 16 upon a standard 17, said rod being preferably in two parts coupled by member 13 The forward portion of said lever is provided with a foot rest 18 and a rigid pawl 19, the latter adapted to engage the teeth of a ratchet 20 pivotally secured at 21 to a standard 22.

It will be noted that the upper end of said held in engagement with pawl 19 through 1V. BEnNArmn,

the agency of spring 24 connectedfwith ard 17 is sufficiently loose to allow of slight I said lever to permit lateral movement of p of the disengagement of the pawl and ratchet; Mounted upon rod '13 and engag,

that, its capacitymay Y be ncreased or diminished-to anydesired, extent simply by increasing or diminishing the'length of shafts 5 and springs 12-and the parts of this press are readilydetach be easily tage lies in the fact adjustment ofcoup'ling 13 whicl1,' of course,

The second batch be ing ready, the pawl and ratchet are disengaged, the presser-plates are raised by springs 12 and the freshly cemented parts are disposed upon the upper surface of casting 2, whereupon lever 15 is again depressed to bring the presser-plates down upon the shank portion, and that, ,efiectually andratchet I soles. When the operator has forced lever 15 downward as far as possible through the agency of his own weight, he locks it in position by meansfof pawl 19 and ratchet 20 and then brings hub 27 of wheel 26 to bear against collar 2 of casting 2. Obviously, further revolution of said wheel has the effect .of further depressing plates 8, 8 so that extraordinary pressure is exerted upon the soles and it should here be noted that, despite the inclinationpresent in the stacks of soles, as before mentioned, the pressure thereupon is evenly distributed by reason of the corresponding inclination of the under surfaces of saidplates as shown at 9 and 10.

hat I claim as new and desire to secure by Letters-Patent is 2-- 1. A machine of the character described comprising pressing plates, means for forcing the same into engagement with the articles to be pressed, mechanism for increasing the pressure of said plates in supplement to said means, and members adapted to separate said plates and articles after operation of said means and mechanism.

. 2. A machine of the character described comprising pressing-plates, means for forcing the same into engagement with the articles to be pressed, devices for locking said means, and mechanism for increasing the pressure of said plates in supplement to said means. 7

3.'A machine of the characterdescribed comprisingpressing-plates, means for forcing the same into engagement with the arti"- cles to be pressed, devices for locking said means, mechanism for increasing the pressure of said plates in supplement to said means, and members adapted to separate said plates and articles after operation of said means and mechanism.

4:. A machine of the character described comprising a stationary member, a rod projecting therethrough, a pressing-plate secured to said rod, threads upon said rod. extending substantially above and below said member, a lever connected with said rod cured to said rod,

' cally lifting adapted to force said plate into engagement with the article to be pressed, and a wheel freely engaging said threads adapted to bear against said member, whereby the pressure of said plate may be increased.

5. A machine of the character describe-.1 comprising a stationary member, a rod projecting therethrough, a pressing-plate secured to said rod, threads upon said rod extending substantially above and below said member, a lever connected with said rod adapted to force said plate into engagement with the articleto be pressed, devices for locking said lever, and a wheel freely engaging said threads adapted to bear against said member, whereby the pressure of said plate may be increased.
